DRAWING DEVICE R APPARATUS This invention has as its object to provide anew or improved device or apparatus for the purpose of drawing a mu]-tiplicity of straight lines of various and predetermined lengths, andarcs or curves of various and predetermined radii and lengths atmultiple and subsequent predetermined locations on the surface of paperor other suitable material by employing a pen, pencil, or like device,following a predetermined formula, the composite of said lines, arcs,and curves forming a picture, drawing, design, or alphabetic letter. Thedevice may be used for engineering purposes, but was conceived primarilyfor educational and amusement purposes.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a top plan view of the primarymember and two secondary members, one of rectangular shape and oneincorporating a spiral design, showing possible manners of locating thesecondary members to the primary member;

FIG. 2 is a plan view of a secondary member of rectangular shape;

FIG. 3 is a side elevation of FIG. 2.

FIG. 4 is a plan view of a spiral shaped secondary member;

FIG. 5 and FIG. 6 are perspective views of the pegs used in mounting andpositioning the secondary members to the primary member.

DESCRIPTION OF THE EMBODIMENT Referring now specifically to thedrawings, basically the drawing device or apparatus consists of oneprimary member 1 and two secondary member 2 and 3. The primary member 1consists of a flat drawing board which may be made of cardboard, wood,or other suitable material to which paper or other suitable material maybe mounted. Parallel and adjacent to the entire periphery of saidprimary member 1 is furnished a plurality of apertures 4, adjacent andparallel to said apertures there being disposed a scale 5 for thepurpose of identifying said apertures. Said apertures are used formounting, by the use of pegs, the secondary members 2 and 3, which aredescribed herein, to the primary member 1 in multiple and subsequentpositions.

One form of the secondary member (FIG. 2), which is utilized in thedrawing of all straight lines in the picture, drawing, design, oralphabetic letter, comprises a flat, elongated, rectangular shapedtransparent body 2 with a scale 6 inscribed thereon, at one end of saidmember there being an aperture 7 which is used for mounting saidsecondary member 2 to a predetermined aperture 4 of the primary member 1in a pivotal manner by the use of a peg 8. A second peg is then placedinto another predetermined aperture in the primary member and thesecondary member is then pivoted counterclockwise until it restsadjacent to and touching the second peg placed in the primary member.When said secondary member 2 is thus attached to the primary member, inaccordance to a predetermined formula, a desired straight line ofpredetermined length may be drawn at a predetermined location on thesurface of the paper or other material mounted on the primary member 1through the use of a writing instrument by employing the edge of thesecondary member 9 as a guide and observing a predetermined startingpoint and predetermined stopping point on the scale 6.

Another form of the secondary member 3, which is utilized in the drawingof all arcs or curves in the picture, drawing, design, or alphabeticletter, comprises a flat, spiral-shaped element 10 of transparentmaterial and having a scale 11 inscribed on the entire peripherythereof. Said spiral-shaped element 10 is transversed by and mountedbeneath a flat, elongated element 12 of transparent material with ascale 13 inscribed thereon for identification purposes, and having aplurality of apertures 14 for the accommodation of a peg 8 for themounting of said secondary member 3 to the primary member 1 in a pivotalmanner at one point, with said flat elongated element of the secondarymember 12 being butted against another peg placed into another apertureof the rimary member at a second pomt. When sa1 secondary mem er 3 18thus attached, in accordance to a predetermined formula, arcs or curvesof predetermined radii and lengths may be drawn at predeterminedlocations on the surface of the paper or other material mounted on thedrawing surface of the primary member 15 through the use of a writinginstrument by employing the edge 16 of the flat spiral-shaped element 10of said secondary member 3 as a guide and observing a predeterminedstarting point and a predetermined stopping point on the scale 1 linscribed on said spiral-shaped element.

I claim:

1. A drawing device comprising a combination: a flat rectangular shapedprimary member, adjacent and parallel to the periphery of which isdisposed a plurality of identified apertures equally spaced about theentire periphery of said primary member for the accommodation of pegs; aflat elongated shaped secondary member of transparent material with ascale inscribed thereon, and having an aperture at one end thereof forthe accommodation of a peg for the mounting of said secondary member toan aperture of the primary member in a pivotal manner at one point, withsaid secondary member being butted against another peg placed intoanother aperture of the primary member at a second point, whereby, thesecondary member thus positioned, a straight line of predeterminedlength may be drawn at a predetermined location on the surface of thepaper or other material mounted on the primary member, through the useof a writing instrument, by using the edge of said secondary member as aguide and observing a predetermined starting point and a predeterminedstopping point on the scale inscribed thereon.

2. A drawing device comprising in combination: a flat rectangular shapedprimary member, adjacent and parallel to the periphery of which isdisposed a plurality of identified apertures equally spaced about theentire periphery of said primary member for the accommodation of pegs; asecondary member consisting of a flat spiral-shaped element oftransparent material and having a scale inscribed on the entireperiphery thereof, said spiral-shaped element being transversed by andmounted beneath a flat elongated element of transparent material havinga plurality of identified apertures for the accommodation of a peg forthe mounting of said secondary member to the primary member in a pivotalmanner at one point with said flat elongated element of the secondarymember being butted against another peg placed into another aperture ofthe primary member at a second point, whereby, the secondary member thuspositioned, an are or curve of predetermined radius and length may bedrawn at a predetermined location on the surface of the paper or othermaterial mounted on the primary member, through the use of a writinginstrument, by using the edge of the spiral-shaped element of thesecondary member as a guide and observing a predetermined starting pointand a predetermined stopping point on the scale inscribed thereon.
